Why would someone want to use a glass break detector in their
home? - ANSWERS-These SHOCK detectors/sensors can be used to
detect a rapid change of air pressure quickly. It will send a signal to
the contacts and initiate an alarm. Most models aren't too pricey and
can help increase the security value of one's home.
What is a passive Infrared detector - ANSWERS-Detectors that are
sensitive to moving, heat radiant sources, such as people and
animals. They will sense changes in heat through a lens at different
focus points.
What is a normally open loop and a normally closed? - ANSWERS-
N/O: This is when an alarm will go into a contact, such as a magnetic
reed switch, and will close. N/C - this is when it does the opposite.
True or False - Signalling devices are used for homeowners to know
that intrusion is not in process. - ANSWERS-False. They are used to let
the homeowner know.
, Why do electricians install sirens in the cold air return? - ANSWERS-1)
Intruders have a hard time getting in there to disable it 2) This is a
good place to resonate the sound
What is an ionization smoke alarm? - ANSWERS-This device detects
invisible products of combustion or ions if the concentration is high
enough.
True or False: The most commonly sold smoke alarms are the
ionization type because they have many advantages. - ANSWERS-
True. You should know the advantages of these alarms as well.
Yes or No: Do photoelectric light smoke alarms use light lasers to
detect the area to be projected at the same end? - ANSWERS-No.
They use a light beam and project at the opposite end.
What sections and which rules of the 25th Edition Canadian Electrical
code mentions installation of smoke alarms? - ANSWERS-Section 16,
32. Rules 16-210, 16-212, 16-220, 32-100, 32-102, 32-200
Smoke alarms need to be installed... - ANSWERS-1) Each story of each
dwelling unit or near the ceiling 2) In each sleeping room 3) In a
